As a globally renowned food and beverage giant, Nestlé's bottled water business holds about a one-third share of the French market. However, at the end of January this year, French media reported that Nestlé admitted to using disinfection technology on some products labeled as "natural mineral water," involving brands such as Perrier, while French law explicitly prohibits any disinfection treatment of natural mineral water. Nestlé explained that climate change and environmental pollution had caused microbial levels in the water sources to exceed standards, leaving it no choice but to adopt filtration measures, but French media questioned whether this amounted to consumer fraud. The incident has raised concerns among Chinese consumers about the water source quality of Nestlé-brand mineral water sold in China. Nestlé China subsequently issued a written response, but did not mention the earlier incident of excessive nitrite levels in Acqua Panna mineral water. Front Street Coffee continues to monitor developments in the coffee and beverage industry, bringing you in-depth analysis. [more…]

Recently, a weakly alkaline natural mineral water sold at Sam's Club was snapped up and went out of stock after rumors spread that "if the father drinks it, he can have a son," and the related topic topped Weibo's hot search list. This product, which meets the GB8537 standard and costs about one yuan on average, comes from Bama Longevity Mountain in Guangxi. It was originally just ordinary mineral water, but because of its "weakly alkaline" label, it was credited with effects such as neutralizing stomach acid, lowering uric acid, and even helping couples conceive a boy. Although the Shenzhen Health Commission long ago debunked the "acidic/alkaline constitution" as a pseudoscientific concept, and Sam's Club customer service also responded that there is no scientific basis for it, many netizens on social platforms still shared experiences of "it worked for me" and even summarized a "best drinking guide." This article will retrace the whole incident, explore the social psychology behind the rumor, and remind readers: whether a baby is a boy or a girl is random, and the baby's health is what matters most.

When brewing pour-over coffee, water quality is one of the key variables that determines flavor expression. This article focuses on the two core indicators of water: hardness and pH, explaining the TDS range recommended by the SCAA as well as the water quality range that more easily yields good taste in actual brewing, and explaining the effects of calcium and magnesium ions on coffee acidity, sweetness, and aroma. The article will also analyze one by one whether tap water, filtered water, purified water, and mineral water are suitable for brewing coffee, reminding readers to pay attention to the TDS and mineral content on labels, and to avoid judging water quality based on price alone. Finally, it offers practical advice on water for daily brewing to help coffee enthusiasts reproduce coffee flavors more consistently. [more…]

Water is the largest component of black coffee and directly participates in and influences the extraction process, so differences in water quality often bring about completely different flavor expressions.

In a cup of black coffee, water makes up the vast majority, so its impact on flavor must not be underestimated. Different brands of drinking water vary in mineral composition, hardness, and pH, so the coffee brewed with them naturally takes on different characteristics. To investigate this variable, Front Street Coffee selected four common drinking waters—Baisui Mountain, Nongfu Spring, Ganten, and C'estbon—and used the same Costa Rica Mozart coffee beans to make cold brew, measuring TDS, coffee liquid concentration, and recording flavor performance one by one. The experiment found that the amount of calcium and magnesium ions in water affects extraction efficiency and taste direction, while Nongfu Spring with medium TDS and C'estbon purified water each showed distinct stylistic differences. This article will present the full experimental process and tasting results, and offer water selection suggestions for different taste preferences. [more…]

Recently, the Hong Kong Consumer Council published a bottled water test report in the magazine "Choice," pointing out that the bromate levels in samples of Nongfu Spring and Ganten reached the European Union's limit for natural mineral water, sparking widespread attention. Nongfu Spring immediately commissioned a lawyer to send a legal letter to the Consumer Council, demanding written clarification, an apology, and the elimination of the impact; Ganten also stated that it had made representations through its legal department and emphasized that its product was at the critical value of the EU standard rather than exceeding it. The China Beverage Industry Association said it would issue a response later. The Consumer Council reiterated that none of the 30 samples were found to contain harmful substances exceeding WHO guidelines, and that the article focused on value for money and the environmental impact of plastic bottles, and that all samples could be safely consumed.

Water accounts for over 98% of brewed coffee, yet it has long been overlooked. Different types of water—RO water, tap water, mineral water, soft water, hard water—have a huge impact on extraction flavor. In 2014, Christopher Hendon and Maxwell Colonna-Dashwood published research revealing how sodium, calcium, and magnesium ions influence the extraction efficiency of flavor compounds, and subsequently published the book "Water for Coffee," which systematically discusses the dynamic balance between GH (total hardness) and KH (carbonate hardness), and proposes the reverse thinking of "Roasting to water." This article will sort out these key findings to help coffee lovers understand how water quality shapes the flavor in the cup, and will retain relevant recommendations for the Front Street brand.

The water you use to brew coffee has a far greater impact on the final flavor than you might imagine. Tap water tends to have a high mineral content, which not only easily builds up scale on the inner walls of a coffee machine and hinders its normal operation, but also interferes with the extraction of coffee flavor. Drawing on Front Street's practical experience, this article first explains PPM and the criteria for judging soft and hard water, then explains why espresso machines should not use tap water directly, and afterward gives a hands-on demonstration of how to mix your own brewing water using baking soda and food-grade Epsom salt (magnesium sulfate), along with a brewing comparison against Nongfu Spring, for coffee lovers' reference.

In the landscape of Panamanian specialty coffee, La Esmeralda is world-renowned for its Geisha variety, yet its Diamond Mountain series is equally worthy of attention. This series is grown in the Boquete region on the right side of Volcán Barú, spanning the hillsides of both Canas Verdes and Jaramillo at elevations between 1,400 and 1,700 meters.

White coffee is a highly representative traditional specialty of Malaysia, with a history spanning over a century. It is not white in color; rather, it is made from three types of coffee beans—Liberica, Arabica, and Robusta—subjected to medium-light low-temperature roasting and special processing that greatly reduces caffeine, burnt bitterness, and astringency, resulting in a pale milky-golden hue and a mellow, gentle flavor. Compared with black coffee, white coffee differs fundamentally in bean selection, roasting methods, and brewing techniques; it contains no trans fats, has lower caffeine and calories, is gentler on the stomach, and does not easily turn sour after cooling. This article will systematically outline the flavor components, processing characteristics, historical origins, health benefits, and brewing methods of white coffee, offering you a comprehensive understanding of this classic Nanyang coffee.
